Lithium-ion batteries are particularly sensitive to overcharging and discharging, so avoid charging more than 100% or discharging less than 20%. Charging when the battery power drops to about 30% is recommended. Keeping battery power between 40-80% can slow down the battery’s cycle age. 2. Control charging time
Li et al. proposed an electrochemical–thermal coupling model for LiCoO 2 battery, which combines lumped thermal analysis with a simplified electrochemical model. Besides, mechanics can have a critical influence on the performance and the lifetime of lithium-ion batteries .
One approach seemingly well-suited to this task is model predictive control (MPC), which is gaining popularity throughout industry . In Ref. the authors propose a nonlinear model predictive control approach to minimize the charging time of a lithium ion battery based on a complex underlying electrochemical model.
The charging method of both batteries is a constant current and then a constant voltage (CCCV), but the constant voltage points are different. The nominal voltage of a lithium iron phosphate battery is 3.2V, and the charging cut-off voltage is 3.6V. The nominal voltage of ordinary lithium batteries is 3.6V, and the charging cut-off voltage is 4.2V.
A knowledge-based, multi-physics-constrained fast charging strategy for lithium-ion batteries is proposed , which considers the thermal safety and aging problems. A model-based state observer and a deep reinforcement learning-based optimizer are combined to obtain the optimal charging strategy for the battery.
In the middle is a polymer separator that separates the positive and negative electrodes. Lithium ions Li+ can pass through, but electrons e- cannot. On the right is the battery’s negative electrode, composed of carbon (graphite) and connected to the battery’s negative electrode by copper foil.
